Create a highly detailed, 3D render of a muscular, male undead cyborg with exposed bones and black armor, in the style of Beksinski, Moebius, and Greg Rutkowski. The cyborg should be connected to heart machines, have a large bust, and be depicted in a dark, eerie atmosphere reminiscent of the Souls series. Incorporate elements of Transmetal II and Berserk, and ensure the artwork is SFW. The style should be a mix of remodernism and cyber octane render, with an Unreal Engine aesthetic. The final output should be a large, intricate artwork.
